In the wake of the depression of 1929, four friends gather in a cold, dusty attic on Christmas day to make a solemn pact. Our dreams for the future, they whisper, as they place tiny pieces of paper holding their life wishes into the blue, cabin-shaped bottle. Letitia dreams of marriage and children; Mary hopes to be a painter; Eleanor aspires to help those in need as a social worker; Adora longs to be a Broadway actress. Four girls, four dreams, and four futures sealed in a cobalt blue bottle. Sixty-five years later, local news reporter Brendan Delaney stumbles upon the bottle, discovering the most meaningful story of her career and possibly the meaning missing from her own life.
